Abstract

A method for operating a vehicle which has at least one steered axle and at least one driven axle, wherein at least the driven axle has at least two wheel-hub electric motors that are integrated in the respective drive wheel. In addition, an electronic control unit (BLDC controller module 1, BLDC controller module 2) is provided for the wheel-hub motors (wheel-hub motor 1, wheel hub motor 2) forming an electronic differential. Sensors detect signals (Hall signals) that correspond to the driving defaults. Correction factors for default values for controlling the wheel-hub motors are determined from the sensor signals (speed), the position of the accelerator pedal (gas pedal) or accelerator throttle and the steering angle (steering angle generator) by an interface module and the factors are forwarded to the relevant motor control units (BLDC controller module 1, BLDC controller module 2).
